His head teacher, Jim Turner, from King’s Hawford Junior School, in Worcesterhire, told the Birmingham Mail that the youngster is making a “miraculous recovery”.

Mr Turner, who visited George armed with audio messages on Monday, said: “It was uplifting. He is fine and he will be fine.”

George, from the Warwickshire village of Cookhill, does not understand the enormity of the January crash near Popham Airfield, Hampshire.

It is believed the accident happened as the light aircraft was making its way back from the Isle of Wight.

Both Lewis, who celebrated his 50th birthday on New Year’s Eve, and 44-year-old Sally were pronounced dead at the scene.

George was initially treated at Southampton General Hospital, but transferred to Birmingham Children’s Hospital over the weekend.

Mr Turner, who held a special assembly to talk to pupils about the accident, said: “George was in really good spirits.

“Initially, he was very poorly - at one time critical, but he has made a miraculous recovery.”

The moving messages from friends have proved an enormous help on the long road to recovery. Mr Turner added: “George was really pleased to hear familiar voices, friends talking about the games they like to play, such as ‘tickle monster’ and football.”

In a statement on its website, the school told parents and pupils: “George will need the support of his family and also of the school community as he recovers from both his physical and emotional injuries.

“He has many strong friends in both his class and his year group. At this time we will need to be strong for each other and also for George and his family. We are fortunate to be such a tight knit community. At moments of great distress this is a source of strength and we must be there for each other. George will need our help and love both in the short term and in the longer term.

Mr Tonkinson was a co-founder of Birmingham City Centre firm Pinnacle Marketing Communications.

In a statement on the company’s website, fellow co-founder Simon Flatt said: “Lewis and Sally were a hugely popular couple and their tragic and untimely loss will leave a big gap in the lives of the great many people that knew and loved them.

“Our thoughts are with their families and, in particular, for George’s speedy recovery.”

Flowers have been placed outside the family’s large, gated home.

Investigations into the plane crash are being carried out by the UK Air Accidents Investigation Branch.
